Morningstar TriStar ^TM

Three-Function Solar Controller

The Morningstar TriStar Controller is a three-function controller that provides reliable solar battery charging, load control or diversion regulation. This controller operates in only one of these modes at a time but two or more controllers may be used to provide multiple functions.
The Morningstar TriStar uses advanced technology and automated production to provide exciting new features at a competitive cost. The controller is UL listed and is designed for both solar home systems and professional applications.

Standard Features:

• Ratings are actual to 50°C and meet UL requirements; no need to de-rate
• Choice of 7 different regulation or LVD setpoints selectable via DIP switches; eliminates troublesome rotary switches and “trim pots”
• RS-232 comm port provides for a wide range of custom setpoints
  • DB-9 connector, 9600 baud
  • Designed for PCs and “Palm Pilots”
  • May be used for:
    • adjusting control setpoints and parameters
    • data logging with 30 days storage (future capability)
    •  remote monitoring and control (future capability)
•  Self-test runs continuously. If a fault is detected, the fault will be displayed on the digital meter and indicated  with the LED’s
• Push button will reset from an error or fault, start or stop battery equalization (charge controller mode) or override LVD (load controller mode)
• 100% solid state for high reliability in harsh environments
• Microprocessor control for extended capabilities
• Conduit-ready enclosure for large wire sizes; provides extra room for wire turns
• Very low voltage drops
• 5 year warranty
• Estimated 15 year life

Load Control Mode:

• Electronic short circuit and overload protection with automatic reconnect
• Starts all loads including inductive (meters, pumps) with no damage to controller
• Allows inrush current to 300A
• LVD has 4 minute delay to avoid incorrect disconnect
• LED and meter indicates LVD warning and disconnect
• LVD is current compensated to avoid false disconnect
• Load protected by an automatic high voltage disconnect
• Load protected from solar voltage spikes when the battery is removed

Digital Meter Option:

• Voltage accuracy is 0.2%
• Current accuracy is 1.0%
• Meter may be mounted to the controller by removing the controller cover plate
• 2 x 16 display with backlighting
• Installs to controller with RJ-11 connector for simple installation
• Includes 4 pushbuttons for easy “up/down” and “left/right” scrolling
• Displays self-test results, system information and controller setpoints
• Remote digital meter for mounting away from the controller (in another room):
  • Flush mount in a wall or fit into a double-gang electrical box
  • Installs with RJ-11 connector
  • Available with a 30 meter cable

Mechanical Specifications:

 Electronic Protections:

• Reverse polarity protection (any combination)
• Solar and load short circuit protection
• All other connectors are short circuit protection
• Solar and load overcurrent protection
• Lightning and transient surge protection using 4500W transient voltage suppressors
• High temperature protection via automatic current reduction or complete shut-down

Charge Controller Mode:

• Constant voltage series PWM to provide highly efficient battery charging
• 4 stage charging to increase battery capacity and life: bulk charge, PWM regulation, float and equalize
• 3 LED’s indicate battery state-of-charge, controller status and battery service required
• Parallel for larger solar arrays up to 300A or more
• PWM may be changed to “on-off” controller to minimize any possible telecom noise
• Temperature compensation via optional remote temperature sensor
• Battery sense connector to eliminate voltage drops between the controller and the battery

Diversion Control Mode:

• May be used for solar, wind or hydroelectric
• To protect against battery overcharge, excess energy is diverted from primary battery to a secondary battery or alternate DC resistive load

Remote Temperature Sensor Option:

 

• Accurately measures temperature at the battery and compensates regulation setpoints
• Cable length is 10 meters; may be increased to 30 meters
• Rated from -30°C to +80°C
• Defaults to 25°C if temperature sensor reading is out of range or fails

Environmental Specifications:

Operating ambient temperature: – 40°C to +50°C; For 60°C, de-rate 20%
Storage temperature: -55°C to +85°C
Digital Meter operating temperature: -30°C to +85°C
Humidity: 100% (non-condensing)
Tropicalization:

• Conformal coating on both sides of all printed circuit boards
• Electrolytic anodized aluminum heat sink
• Powder-coated steel enclosure
• Stainless steel fasteners
